17-1/2" ID X 18-1/2" OD X 3/4" HT

Ordered as L50017500750, this is a Polyurethane (AU/EU) Deep Profile Loaded Lip Seal with a 17-1/2 in inside diameter, an 18-1/2 in outside diameter, and a height of 3/4 in. The loaded lip seal delivers low-friction dynamic sealing with strong resistance to pressure spikes. Source specification: Loaded Lip Seal (deep) Urethane.

The material holds up against abrasion and wear, petroleum oils, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) is specified for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. It is not the right choice where ketones or prolonged humidity at elevated temperature are present.

You will find this material specified across high-pressure fluid power, construction machinery, and press and forming equipment.

This item is sold individually under part number L50017500750. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
